304SS 2.5" 0-3,000 PSI/ 0-210 Bar Liquid Filled Pressure Gauge, 1/4 NPT Center Back Connection

Description & Features

The 304SS liquid-filled pressure gauge features a 2.5-inch dial and measures up to 3 000 PSI/210 Bar. Engineered for precision this gauge employs a 304 stainless steel casing ensuring durability and resistance to corrosive environments.

The liquid-filled design helps in damping the effects of vibration and pressure spikes enhancing the longevity and accuracy of the readings. A 1/4 NPT center back connection made of brass with a 0.013" throttle plug ensures secure and reliable installation.

This gauge is designed with polycarbonate window material providing clear and easy readability while protecting the internal components. It offers an accuracy of 3-2-3% of span which translates to 3% over the first and last quarters of the scale and 2% over the middle half of the scale.

Normal operating pressure should be confined to 25%-75% of the scale. For applications with pulsation gauge pressure shouldn't exceed 50% of the full-scale range. The gauge is not pre-calibrated and does not include a case.

Question by: Tony W on Sep 28, 2025, 8:40 AM
Reckon this gauge will hold up outside?
Answer by: Customer Support on Sep 29, 2025, 10:04 AM
The casing is made from 304 stainless steel, which should give you good corrosion resistance in outdoor settings.
Question by: Rick W on Feb 24, 2026, 6:48 AM
gauge says center back connection, does that mean the port comes straight out the back, center of the dial? trying to figure out mounting before I order
Answer by: Customer Support on Feb 25, 2026, 10:13 AM
the connection comes out the center of the back of the gauge, not the bottom or side. That makes it real straightforward to mount flat against a panel or panel bracket with the line running directly into the back. The thread is 1/4 NPT brass, so as long as your fitting matches that size and thread type, you're in good shape for installation.
